In some cases, the number of lamps that light up will decrease.※See graph 2soft groundNumbers of compaction-Gravel(C-40)-※Product features:MVH-308DS-PASCompaction limit Poorground or soft groundYellow lamp: 1-8Red lamp: Illumination※See graph 1Relationship between moisture content and compaction［Remarks］ The LED lamps of the compaction sensor do not show the absolute value of the soil rigidity. When using this machine always conduct tests such as the plate load test and dynamic load test (FWD) to determine the correct soil rigidity suitable for the work, and do calibration of the actual measured value and the LED illumination level.movie810m2/hour1050m2/hour1360m2/hourMoisture content 4.5%15050100200Ground reaction coefficient; Equivalent to K30 (MN/m3)Optimummoisturecontent200100250Excessmoisturecontent ratio（Reference）Pass（No. of compaction）20Operating WeightMODELCentrifugal kgMT-55H62MT-66HL72MT-77HRL77MVH-308DSY341MVH-408DSY407MVH-508DSZ525Crushed stoneImpact ForceWidthForcekgfmmm (A)10002650.26513002850.28514002850.28546004450.44551005000.50066006500.650Acceleration sensorTravel SpeedTravel Distance/Compaction Area/hourhourm/minm (B)11660174.913780222.312720205.2271620720.9271620810.02917401131.0The number of LED lamps that are lit is proportional with the soil rigidity.If the moisture content of the soil is too high, its rigidity may drop even after compactions are repeated, and because of this, the number of illuminated LED lamps will also decrease.■Extension PlateFor MVH-308, 408, 508 (75,150mm)※MVH-508 is equipped Extension Plate 75 mm as standard.Relationship between soil rigidity and LED lampsCompaction Area/Hour①0.285m (A) x 12m /min. x 60min. /hour = 205.2m2 /hour②0.500m (A) x 27m /min. x 60min. /hour = 810m2 /hour粘土質■Extension Plate■Compaction Sensor "Compas II"Saving your time
